This invention relates to machines for washing clothes and the like ofthe type having a stationary tub and an oscillatory dolly provided witha plurality of fins or baffles.

Q The invention has particular reference to an improved dolly.

The general aim of the invention is to provide an improved constructionwherein clothes or other articles may be quickly and loefi'ectivelywashed and cleansed without injury thereto.

More particularly, the aim of the invention is to provide a washingmachine with an improved dolly which gives the water and the clothesimmersed therein a constant rolling effect or motion which produces thebest results and hastens the cleansing without danger of injuring theclothes, even the most fragile and soft materials; which sets up a freeagitation and directs the currents in such manner as to cause the fluidto penetrate the clothes and thoroughly cleanse them; and which preventssnarling, tangling or bunching up of the clothes and all possibility ofthe clothes wrapping themselves about the dolly, it having been foundthat tapes, strings and the like may be put in among the clothes withoutany tendency of these string-like articles clinging or coilingthemselves about the dolly.

We have found from extensive tests that our improved dolly eliminatesmany disadvantages and objections incident to machines of this typewhich are now on the market.

Other objects will be in part obvious and in part pointed out more indetail hereinafter.

The invention accordingly consists in the features of construction,combination of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth and the scope ofthe application of which will be indicated in the appended claims.

In the accompanying drawings, wherein is shown, for illustrativepurposes, one of the many embodiments which the present invention maytake, it being understood that this disclosure is by way ofexemplification only:

1 Figure 1 is a side elevation of the improved dolly;

Fig. 2 is a planview thereof;

Fig. 3 is a vertical sectional view through the dolly and the mountingtherefor; and

Fig. 4 is a sectional view through one of the ins, this view being takenon line 44 of Referring to the drawings in detail, the numeral 10designates a tub of suitable size and shape. It is preferably round andhas its upper edge extending above the top of the dolly. The tub may besupported on a base 11. Arising centrally of the tub and preferably to apointabove the waterline, (designated by the line a2:z2) is a tubularsupport or sleeve 12 in which is journalled a shaft 13 adapted to beoscillated about a vertical axis in any suitable manner, the mechanismfor oscillating the shaft and the dolly connected thereto not beingillustrated as it may be of any suitable construction. Secured to theupper end of the shaft 13 is a polygonal, for instance a square, bushing14 adapted to be received by a similarly shaped hole 22 in the top ofthe dolly so that, when the dolly is in position, the shaft and thedolly will oscillate in unison. At the lower end of the support 12 is aflange 15, the upper surface of which may form a bearing for the spider23 mounted in the lower end of the dolly. The construction so fardescribed is shown for illustrative purposes only and may be changed.

Reference will now be had to our improved dolly wherein the gist of thepresent invention resides. In the present illustrative disclosure, thisdolly has a disk-like plate or base 20 and a generally cylindricalstandard or stem 21 arising centrally thereof. The upper end 21' of thestandard is generally tapered or dome shaped, thus making it more orless rounded so as to avoid sharp corners or angles. By preference, thestandard is of susbtantial diameter, in the present instance, thediameter of the standard being only slightly less than the radius of thebase 20. The upper end of the standard has a square hole 22 adaptedtoclosely receive a bushing 14 on the upper end of the drive shaft. 1Suitably secured in the lower end of the dolly and resting upon theflange 15 is a spider 23.

The'dolly has a plurality of agitating fins A, preferably three innumber and equally spaced apart, and these fins are of particularconstruction in order to obtain the best result in operation. Each ofthe fins extends generally radially of the dolly and has a body portionwhich is inclined upwardly from the outer edge of the base toward thestandard. The body portion of each fin has inwardly curved or concaveside walls 25 which diverge as they progress toward the standard. Thusthe body portion of each fin increases in width from its outer edge 26toward the standard and tapers down in width from its lower end to itsupper end. The upper ends of the fins merge into the standard at a pointspaced a substantial distance from the top of the standard, in thepresent instance these fins being about two-thirds of the height of thestandard and merging into the standard ad 'acent the lower end of itstapered portion 21. Each fin has extending from the lower portion of theouter edge of its body portion a flat lobe 27 which preferably extendsbeyond the edge of the base. The upper edges 28 of the lobes graduallymerge into the respective outer edges of the body portion of the fins.

The lower ends of the side walls of the fins are susbtantiallytangential to the standard, as will be most clearly seen in Fig. 2. Theupper end of the standard may be provided with 2. ca 30 having athreaded stud 31.

With t e arrangement described, when the dolly is oscillated, the-water,together with the clothes carried thereby is caused to travel generallyoutwardly of the dolly at the bottom of the tub, then upwardly alongtheside of the tub, then inwardly towards the dolly, and then downwardly ofthe dolly so that substantially continuous currents are set up which areso directed that the clothes are caused to travel with more or less of arolling motion. Owing to the peculiar shape of the fins, the water hasmore or less of a sweeping action as it passes over the sides of thefins. The relatively fiat vertical lobes accelerate the radial movementof the water at the bottom of the tub. It will be observed that thedolly is substantially devoid of ockets or dead spots in which theclothes mlght bunch up or collect or in which a free and completeagitation of the water may not be had. From actual use of the apparatus,it has been found that the circulation of the water is relatively rapidand is such as to maintain the clothes in a more or less spread outcondition, insuring that the water may be caused to penetrate allportions of the clothes and efi'ect cleaning to the best advantage. Theclothes do not tend to cling, collect or wrap themselves about thedolly. In the event that a blanket or other large article should beplaced or find its way over the top of the standard, it would begradually and gently withdrawn therefrom and put into circulationwithout any danger of the article wrapping itself about the dolly orbecoming torn or otherwise damaged.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be inter preted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the followingclaims is intended to cover all of the generic and specific features ofthe invention herein described and all statements of the scope of theinvention which, as a matter of language, might be said to falltherebetween.
